lMPFOVEMENT IN FASTENING HINGED, SLIDING, OR OTHER BODIES.

Specification forming part of Letters Patent No. L11,45 I, dated February 2, 1864.

To all whom t may concern:

Be it known that I, LEANDER R. STRE ETER, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and and use my invention, I will proceed to describe its construction and operation.

l denominate it the revolving self-acting ball-bolt.7 Although this principleor mode admits of other forms of application, yet the manner in which I apply it, wherever possible, is as follows Into theA edge, say, of a door, B, I bore a hole, A, of a size sufiicient to admit the spring j', the socket or cup g, with the shank 7L, and concave i, and the ball e, all confined in said hole by the plate j, through which the ball, being forced outward by the action of the spring, is allowed to protrude a portion of its diameter sufficient to enter the plate or socket C, inserted in and fastened to the door-frame D, and forming the catch.

The socket in the frame of the door may have a metallic lip, K, to receive the first Both the metallic ring of the balls diameter. When necessary, I employ two or more of the ball-bolts combined as above. To meet the shrinkage,77 I make the socket in the door-frame of metal or other material, and sufiicient thickness to be projected when required. To meet the sagging,77 I make the aperture in the door-frame socket sufficiently elliptical to be always adjusted to receive the ball. I

The principle of action ot' this new mode of fastening by a iball-bolt is that of a journal and a box, made self acting and adjusting by a spring. The handleor knob being stationary, all that is required to open a door is to pull upon the knob, or to raise a window, lift it, and vice versa, the ball revolving and sinkinginto its socket returning again the moment it is opposite the socket in the frame, thus bef coming a very efficient and novel bolt.

In the drawings, Figure 1 is the face of a door; A, the socket; I, the metallic ring. Fig. 2 is the door-frame, D, the frame; O, the socket; K, the lip. Fig. 3 is the ball.v Fig. 4 is the shoulder or cup; I, the concave face; H, the pintle. Fig. 5 is the spiral spring. Fig. 6 is the whole in position to work.

The small letters in Fig. 6 represent the capital letters in the other figures.

What I claim, and desire to secure by Letters Patent, is

The fastening of hinged, sliding, or other bodies by means of a ball confined in a socket and operated by a spring, substantially as described.
